xhost + command not found如下是一个示例：
原本我以为在没有联网的情况下、不能使用yum 的、可能是本地配置了yum 了吧也可以使用
1. [oracle@11GR2-test ~]$ export DISPLAY=192.168.181.128:1在虚拟机中安装ORACLE, 设置完DISPLAY变量后,运行xhost +命令无法找到,明显为xhost相对应的rpm包未安装.用yum命令加参数whatprovides 加xhost查到相对应的包为xorg-x11-server-utils-7.7-14.el6.x86_64,如下图.2.

5．配置DISPLAY
export DISPLAY=192.168.1.200:0.0
[root@oracle11 ~]# export DISPLAY=192.168.1.200:0.0
[root@oracle11 ~]# xhost +access control disabled, clients can connect from any host
